Were is fuel relay located so I can change it on my 97 pontiac firebird

The Fuel Pump relay is located in the underhood electrical center #2 (front driver's side corner). GM does not provide an official "testing" of the relay, however, you can swap it out with the A/C Compressor Relay (should be the same). If the pump does not run after swapping the relays, remove the fuel cap and turn the ignition to the "ON" position (without starting the vehicle) and listen inside the fuel tank for a 2-second prime (it'll make a hummmm noise). If this noise is not there, it's very likely the pump itself is faulty.
